Our mobile home and rv park is basically a senior cooperative and has 45 RV lots to rent. Generally about 80% of the rv lots are rented. There are 320+ lots in total. The share holder lots are 95% full. Our maintenance fees are quite reasonable and the there is not a lot of properties for sale.
We are getting quite a few inquires from non-rv people wishing to rent a place for short duration stays, but the supply does not match the demand. A lot of our RV renters are regulars with a few new ones each year.
I think the biggest barriers for the RGV are the negative publicity caused by proximity to Mexico, the demographics of the mid-western farm population, and the costs to pull an RV.
